my hero at the moment is ricky;we work together. i was thinking of leaving the place where i work because of our horrible new boss. he is always in a bad mood and he never has a good word to say anyone. he also picks on young female members of staff: there is a girl called kimberley who is terrified of him. or a least she was. when ricky joined us, everything changed. first he covered for me when i was late back from lunch by telling the boss that i was downstairs in the photocopying room. then a couple of days later the boss was standing at kimberley is desk, shouting at her, telling her she was lazy and would have to stay late to finish her work... anyway, ricky marched straight up to him and told him he was a pathetic coward for talking to him stuff like that. well, the boss was stunned to silence- he just walked off without saying another word and he is left us alone since then.
